If you can reach an outlet, use a compatible adapter and cable. If there’s no outlet, use a charged power bank that works with your phone. Wireless charging and a computer connection may also work, but only on supported devices. If you’re flying, check the rules for your airline and route before packing or using a power bank.

Choose a charging option based on what’s available

Option What you need Best when Important limitation
Wall outlet A compatible charging adapter and cable An outlet is available, such as at a hotel, café, airport, or other public location You depend on access to a suitable outlet; cable and adapter compatibility vary by phone.
Power bank A charged, compatible portable battery and cable You can’t reach an outlet You must carry and recharge the battery. Useful capacity and compatibility depend on the specific power bank and phone.
Wireless charger A wireless charger and a phone that supports it You have a compatible charging pad available Not supported by every phone. Apple lists wireless charging as an iPhone charging option; check your device’s instructions. Apple’s iPhone charging guidance.
Computer connection A computer and a cable that fits the phone A computer is available and its connection can supply power Device and computer behavior vary. Apple lists connecting an iPhone to a computer as an option; check your phone’s instructions. Apple’s iPhone charging guidance.

Charge from an outlet or public charging spot

Use a compatible adapter and cable with a wall outlet. At a shared location, use a legitimate available outlet or charging station. A personal adapter and cable are a straightforward way to use a wall outlet when one is available.

Check your phone’s connector and the adapter’s compatibility rather than assuming one cable fits every phone. Apple recommends using compatible charging accessories and provides guidance on Apple USB power adapters.

Use a power bank when there’s no outlet

A power bank provides portable power when an outlet isn’t available. Choose one compatible with your phone and connector, and make sure it is charged before you leave. A power bank’s useful capacity depends on the particular battery and phone, so there is no reliable universal number of phone recharges to expect.

Charge safely

  • Use compatible charging equipment that is compliant and undamaged.
  • Keep the phone, cable, adapter, and power bank dry, and charge in a ventilated area.
  • Stop using a damaged cable or charger. Apple warns that damaged accessories and charging in moisture can cause fire, electric shock, injury, or damage to the device or property. See Apple’s charging safety guidance and adapter guidance.

Check power-bank rules before flying

Power banks are spare lithium batteries. Aviation rules differ by jurisdiction, and airlines may impose stricter limits than general guidance. Check the rules that apply to your airline and itinerary before you travel.

U.S. passenger guidance

The FAA’s passenger guidance, accessed 4 October 2026 and displaying an update date of 2 October 2026, says spare lithium-ion batteries of up to 100 Wh may be carried without airline approval. Batteries from 101 to 160 Wh require airline approval, and passengers are limited to two spare batteries in that range. Spare batteries must be carried in the cabin, not checked baggage. Review the FAA’s current passenger guidance and check with your airline.

Singapore’s Civil Aviation Authority says that, effective 15 April 2026, passengers departing Singapore may carry no more than two power banks and must not charge power banks onboard; it also advises against using a power bank to charge devices during flight. Check the ICAO announcement and Singapore CAAS guidance, along with your airline’s rules.

For domestic flights in China, the CAAC says that, since 28 June 2025, power banks without clear CCC markings and recalled models or batches are prohibited. This is a China-specific rule, not a global requirement; see the CAAC notice.
